ADR-0087 exemption (no-migration-prescription): Nothing authorable changes spelling or type: `packages/spec` is untouched, the start node's `config` stays the open record it was, and `hookId` and `secret` are read from it exactly as before. What changes is runtime behaviour for one authored shape, an `api`-kind flow whose start node carries no `config.secret`, which is now refused at registration and at arm time. `objectstack migrate meta` could not rewrite that shape even in principle, because the missing value is a shared secret only the author and the sending system can supply. The other categories are closed on facts: both packages publish (not `unpublished`); no ADR-0087 id covers this shape and none is minted here (not `registered` / `already-registered`); and the change is runtime behaviour, not a TypeScript declaration (not `runtime-interface-only` / `type-surface-only`).
